Abstract

We experimentally demonstrate the generation of radially polarized Bessel–Gaussian beams from a c-cut Nd:YVO4 laser with a hemispherical cavity configuration by proper mode control. The output beam has an annular-shaped intensity distribution with radial polarization. When the beam is focused, the intensity pattern changes to a multi-ring, which is a typical characteristic of the lowest transverse mode of vector Bessel–Gaussian beam. Higher-order modes of vector Bessel–Gaussian beam are also observed from the same cavity by slightly changing the cavity alignment. The experimental results show a good agreement with the simulation results for both focal and far fields. The present method is a simple and direct way for generating vector Bessel–Gaussian beams.
